Abstract
The injector is a key component of the diesel fuel oil injection system, which directly affects the performance of the diesel engine. And the needle valve is a vital part for the injector. In order to analyze the effect of the needle valve parameters on injection performance, the simulation model of a certain type diesel injector was established based on AMESim. And a simulation for a whole injection cycle of this injector was performed, thus the injection characteristics and the relevant information about motion of the needle valve was obtained. The effect on the velocity of the needle valve, the flow rate and the quantity of the fuel oil injection, etc. had been analyzed by changing the needle valve parameters such as the preload of the pressure regulating spring, the needle valve diameter, and the orifice diameter. The analysis would provide some references in structure design, optimization, test data analysis and fault diagnosis.
